This invention-relates to a door'reenf0rcmg device designed. primarily tor use in the reenforcementof doorsintenjded. for cold storage rooms or the like,and thepurpose of the invention is to provide attachingmeans for a diagonal metal brace bar which serves to preventanydirecttransmiss1on of temp peraturethrough the door, or sagging of the oor.-

The door isianchored atits upper end within the upper inner corner of the door, and at its lower end within the lower outer corner,

and the device of the present invention is in tended to be imbedded within the door framing in such away as to secure a firm and solid anchorage at these points and to make provision for the attachment of the-ends of the brace bar. j

The device is designed with a view to' affording' convenience in insertion into place,

, and with a view to the avoidance of screws,

bolts, or like connections The device, furthermore, is designed to so engage the wooden frame of the door as to prevent splitting of veal the brace bar; and

the wood when subjected to strains, and to afford a rigid, durable and eflicient connection for the brace bar.

Further objects and details of the invention will appear from a description thereof,

in conjunction with theaccompanying drawreenforced on the inside by a stiffener 11' which affords a ledge or shelf 12 to which the lining strips '13 are secured. 1

The outer face of the door is in the form of a panel lwhich is secured by tongue and groove connection to a stile 15, whichin turn is screwed or otherwise rigidly secured to the door side of the abutting stiifener. The

stile afiords an overlapping flange 16 which receives a packing strip or gasket 17, which abuts against the face of the door casing. These details are common in the construction of doors of this character and need not be further described in detail. The door is preferably filled with cork insulation or other packing of the character used for such purpose.

The door is braced by means of a diagonal brace bar 18 of angle iron, comprising a back ing flange 19 which abuts against the door panel, and projecting flange 20 which ex,- tends inwardly toward the interior of the door. The ends of the brace bar extend closely to the corners and are. secured at each end to an anchor 21 which. particularly constitutes the subjectmatter of the present in vention,

The anchor comprises a dru1n-shaped head 22 from which extends a neck 23 which is preferably of a thickness equal to thethickof the head 22 and of less width. The

neck23 merges into a diagonally extending arm 24: of less thickness than the neck, to afford shoulders 25 on each side where the arm merges into the neck.

The arm terminates in a head 26 provided with an aperture 27adapted to receive a bolt 28, thehead 29 of which is countersunk into the backing flange 19 of the diagonal. brace. Theholt passes through the aperture 27 and receives a nut 30 which serves to lock the anchor to the adjacent end of the brace bar and to bring the arm 24 and head 26 into flatwisc relation to-the backing flange 19. The

anchor thus occupies a position within the angle of the diagonal brace and afi'ords a firm and rigid attachment therefor. The drum head 22 is fitted within a cylindrical recess 31 formed by drilling inwardly from the base of the door side before theattsuibmeut of the stile, and the neck 23 occupies a recess 32 cut into the stiffener 11.

The recess 32 is of reduced width but of equal depth with the recess 31 into which it merges, which configuring of the recesses affords space for the socketing of the anchor head andv neck, allowing the arm 24 to projeetinwardly toward the interior of the door in position to make connection with the adjacent end ofthe diagonal brace bar. The

' anchor thus fits snugly within the heavy side portion of the door structure when the stile is in place the anchor will be completely enclosed and imbedded within the woodwork of the door into which it fits snug- 1y, so that no opportunity for movement or displacement is afforded I 1 The drum-shaped head is larger than the neck, and the strains are directed in a diagonal line, so that any tendency toward dis placement will be'resisted by an adequate thickness of wood to prevent splitting Oren-- larging or" the apertures even when severe strains are encountered.

The'device issimple in construction, easy of application, inexpensive, and well adapted for the purpose intended. a
